What type of cloud infrastructure comprises two or more deployment models?

A hybrid cloud is a type of cloud infrastructure that integrates two or more deployment models, such as public clouds, private clouds, and on-premises resources. This architecture allows organizations to leverage the strengths of each model while maintaining flexibility and control over their data and applications.

For instance, a company may choose to run sensitive data and critical applications in a private cloud for enhanced security and compliance while using a public cloud for less critical workloads or to handle variable demand. This combination provides the ability to scale resources dynamically, optimize costs, and improve overall efficiency.

Multi-cloud, while sometimes confused with hybrid cloud, specifically refers to the use of multiple cloud services from different providers, which can include a mix of public, private, and community clouds but does not necessarily integrate them into a single architecture. Public and private clouds refer strictly to single deployment models, emphasizing either shared infrastructure (public) or dedicated resources (private). Therefore, hybrid cloud is the correct type that comprises multiple deployment models working together.
